(NOAA Climate.gov, based on NWS CPC data). This was aligned with the Farmer's Almanac predictions, which stated that January 2022 would be hit with frigid temperatures. But now, we will look at actual Winter snowfall predictions from the latest forecast models. Yes, Tucson is in the part of the Southwest where the La Nina dry signal is usually quite reliable. As the monsoon rain band is situated south of the Equator, the Mekong sub-region . Rare 'Triple-Dip' La Nia Increasingly Possible - The Weather Channel Also, the southwest is expected to be dry during the winter months, which won't help the drought.

One of the main features of the UK's weather this year has been the seemingly indomitable prevalence of mild conditions, which has catapulted 2022 into strong contention for the warmest year on record. La Nina is a climate pattern that originates in the Pacific Ocean but impacts the global weather forecast. This is mainly a result of warmer-than-normal temperatures expected in late Winter by UKMO in the south/southwest. This atmospheric river onslaught surprised many who were expecting a dry season, especially in the Southwest, not only because of the prolonged drought, but also because La Nia tends to bring drier-than-average winter conditions to the region.

Feeling cold. This is calculated as the deviation of the 30 ensemble members from the average for each individual La Nia event, and so I wind up with a total of 630 deviations from the ensemble average that capture precipitation variations resulting from the uncertainty in the initial conditions, i.e., chaotic weather variability. This is an interesting question, and perhaps sometime Nat will have a chance to look into it. NOAA Climate.gov image, based on analysis and data provided by the Climate Mapper website.

Despite the headlines, the winter weather predictions from both publications have a lot of similarities this year. The jet stream is a large and powerful stream of air (wind) at around 8-11km (5-7mi) altitude. A larger deficit can be seen over northern Europe and the Alps. Again, you can see more snowfall than normal, covering a large area from western Canada down into the northwestern United States and the far upper Midwest. With the La Nia climate pattern still in place, drought conditions may also expand to the Gulf Coast.. That doesnt mean that the different flavors of La Nia cannot be important for Southwest U.S. precipitation, and its worth trying to better understand the simulated La Nia precipitation variations. Could the jet stream also have influenced precipitation amounts ? First is the ECMWF, and then it is the UKMO. Although it's several months away yet, a typical La Nia winter in the U.S. brings cold and snow to the Northwest and unusually dry conditions to most of the southern tier of the U.S., according. This figure indicates that the Southwest December-January precipitation was below the 1991-2020 average in 13 of 21 La Nias during the period. Places where precipitation was less than the 1991-2020 average are brown; places where precipitation was above average are blue-green The white box defines the Southwest U.S. region (32 - 40 N, 109-125 W) that is the focus of further investigation. As a snow lover, I am jealous of Flagstaff residents, though I suppose many of those residents have a different perspective than I do. So, I did not see any obviously linear effect of La Nina amplitude in the observational analysis. This U.S. Winter Outlook 2021-2022 map for temperature shows warmer-than-average conditions across the South and most of the eastern U.S., while below average temperatures are favored for southeast Alaska and the Pacific Northwest eastward to the Northern Plains.

Also, we still seem to be transitioning out of La Nina, which may also have some impact. NOAAs new supercomputers are enabling us to develop even better, more detailed forecast capabilities, which well be rolling out in the coming years.. If the response is linear and the normal response is dry, one would expect the wet La Nias to be more likely to be weak ones and the very dry La Nias to be more likely to be strong ones.

Confidence remains very low during this period. Today's Forecast for Tucson Arizona - kgun9.com This figure indicates that SPEAR produces very wet early winter conditions in the Southwest for some of the La Nia simulations, with the largest differences between the wet and dry groups exceeding twice the 1991-2020 climatology (more than 200%). You can see a strong high-pressure system in the North Pacific and a low-pressure area over Canada and the northern United States. Ideas and explanations found in these posts should be attributed to the ENSO blog team, and not to NOAA (the agency) itself. One exception is southwestern Canada and higher elevations in the western/northwestern United States. This calm outlook could well continue, with the Met Office putting the chances of this winter being 'windy' at just 5%. We know that all La Nias feature below-average surface temperatures in the central and eastern equatorial Pacific, by definition, but the details vary from event to event. This connection has been hypothesized, but the evidence is mixed. This question often boils down to whether there were subtle variations in the sea surface temperature pattern that preconditioned the atmosphere for wetter-than-usual conditions in the region (2). The figure below shows that most (13 of 21) of the La Nias from 1951-2020 had below-average December-January precipitation in this region (1), although wet early winters during La Nia .

I agree, a very interesting post! So, next, we want to know if there are any consistent differences in the sea surface temperature pattern between La Nias that lead to wet versus dry early winters in the Southwest. Overall, the UKMO shows a decent snow season across the northern United States. How unusual were these Southwestern wet conditions in the first two-thirds of a La Nia winter? The most important ingredients for snowfall are the air being cold enough and a supply of moisture. We have a proven track record of top and bottom line growth. That means forecasts will bust from time to time, and success or failure must be evaluated over many forecasts. One way we could try to address this question is to group both the wettest and driest La Nias over the Southwest in December-January and then see if there are notable differences in the sea surface temperature patterns that occurred during wetter La Nias versus drier La Nias. The precipitation anomalies are divided into 10 evenly spaced bins, and the number of La Nia events is totaled for each bin. Submitted by rebecca.lindsey on Thu, 02/23/2023 - 10:32. The rest of the United States shows less snowfall than normal, but that does not mean no snow at all.
